Emma Starletto and her stepbrother Nathan Bronson have been fighting since their parents got married, and Emma's mom Dava Foxx is sick of it. She tells the kids that she'd almost rather see them fuck than fight and that they need to get along. Stalking away, Dava returns and hands Emma a piece of paper with a scavenger hunt on it. She says that if the two haven't worked together and finished it by the time she gets home, they'll both be grounded. Emma and Nathan look at the lists and see a bunch of sexy stuff.Emma sees bra and panties on Nathan's list, so she strips and gives him hers. Then she looks at her list and sees a dick pic as one of her items. Nathan obliges, then checks his list and sees that he needs a dildo. Emma disappears into her mom's room and returns with a stick-on dildo. Emma's list says they need Nathan's boxers. He takes them off, then hides in embarrassment as Emma teases him for his small dick. When Nathan swears he's a grower not a shower, Emma decides to find out by stroking him off. When that doesn't give her the instant result she's looking for, Emma starts sucking his cock. Then she says she wants Nathan to fuck her just like her mom said he should. Getting on her hands and knees, Emma watches over her shoulder as Nathan shoves his dick into her. Then she gets on her back and lifts one leg in the air so he can bang her hairy twat as she rubs her clit. Climbing onto Nathan's lap, Emma rides him in reverse cowgirl as her puffy titties bounce with her. She wants him to finish her off on her back, so she goes back to that position and then urges Nathan to pull out and cover her in cum. They're just finishing up when Dava returns and catches them naked, which causes her to freak out that they took her literally.
